CENTRIFUGAL GAS-PURIFIER.

To all whom it may concern:

Be it known that I, FREDERICK V. Ms'rfroN, a sub, ject of the King ofSweden, and a resident of Riverton, Burlington county,.New Jersey, haveinvented certain Improvements in Centrifugal Gas-Purifiers, of which thefollowing is a specification. p My invention relates to gas purifiers ofthe centrifugal type, and the object of my invention is to provide ajstructure ofthe general character shown and described in my formerpatent, No. 775,758, dated November 22,

l to secure fin- I My invention is fully shown in drawings, in which: f

Figure l, is a longitudinal sectional view-of a gas purifier embodyingmy invention, andFig. 2, Vis a transverse sectional view of the same,taken on the line a-a, Fig. 1. i

In the drawings herewith, the chambers forv the inletand discharge ofgas to be treated are indicated at 1 and 2, and except for slightchanges in the position of the fans, it is immaterial whether the gasenters the chamber I and is discharged from the lchamber 2, or takes apathin the opposite direction. In the present instance the arrowsindicate the. directiono Aflow.

the accompanying bows 3 and 4,' respectively, which communicate with theinterior of a central 'casing 5 having hamber's removal of tar or otherimpurities contained in the gas. The casing 5. is made'in two partswhich are 'conof the same and the assembling of the variousparts oftheapparatus. v I,

' The fans are mounted on a shaft 10l adapted to suitable bearings 1lcarried by the elbows 3 and'4, and'in having a series oi long blades 13on oney side and slightly shorter blades 14 on thel other side. Theseblades may be of the same width throughout their length with taas tojust clear the walls of the casing. I, Disposed within the casing 5 andsurrounding the fixed partitions 16 and 17, the-partitions I16 beingsome-v casing 5 is.divided into the compartments or chamfmm' there itpasses inw me elbow 4 leasingfpj'fhej Specification of Letters Paltent.

chamber 2 from which latter it is discharged. The purpose of having the'fan blades of different lengths is to insure the ilow or circulation ofthe. gas, and as vthis feature is fully explained in my former patentabove referred to, there is no necessity for repetition herein.

To `discharge water or other liquid within the fan casing, I provide amain supplyvpipe 20 having three I branches 21, 22 and 23; the branches21-and 23'having nozzles 255whereby the ow of such liquidmay be directed from both sides toward the centerof thecasing, while the branch22 communicates with a passage 26 formed within the division Wall orplate 18 of the casing, from which it is discharged acrossV said openingfor engagement with the gas. immediately passing from one chamber to-thenext.` p The structure is mounted upon a suitable foundation 30, havinga central well 31`iuto which pipes32 from the chambers 6 and 7 of thecasing 5 discharge, and into which othenpipes 33, leading',respectively, from the inlet and outletchambers 1 and 2, discharge; saidwell being/provided', ii desired,4 withan ordinary overflow Y In theoperation of the present form of purifier, the gas enteringthe chamber 1is directed by the elbow 3 into the chamberf of the-casing 5, where itis acted upon in the first instance by the blades 13 of the fan 8, Y

which impart a whirling movement to the lgas and `cause any particles orliquid, such as tar or other iinpuritieswhich are held inzmechanicalsuspension in" the-gas, .to be thrown forcibly `against the fixed partittions 16 of one side `of the ian casing.- The result of this actionis'that the .bubbles are broken up and the liquid or solid particles arecaused toadhere to said partition, from which when they. haveaccumulated in suii'cient volume they drop and finally reach thebottoni` ofl thefanl casing and are thence directed by the pipe 32 intothe well 3,1. After'the gas has been subjeted to Ithe beating action ofthe blades on oneside of the 'rst fan casing it passes to the oppositeside of the same and-.is there subject to a repetition o'f such action,and then passes through "the opening 19 of the partition plate 18 intothe chamber 7, ioraction by therblades of the faut) of the samecharacter as that of the fan-(8, and with corresponding resultsgthepuriied gas finallyescaping through the elbow 4 into the chamberzforsiseyThe of "the rings carrying'the partitions 16 and `17overlap thefan'bladea as shown in Fig. 1, and therevby prevent ,any of the gasvfromgaining access to the .louter chambers of the fan casing without comingunder V theinfiuence of said fan blades.

flhe jets of water orother liquid projected onto the ansby the nozzles25, and between the same from the l e 26 of the partition plate, serveto aid in the 11 separation of thetar or other impurities from the gas iand wash from the fan blades and walls O the casing the impurities whichhave collected thereon, thus pre- .venting the clogging oi the fans byanundue accumuf each of which is occupied by a fan, said'partition meansbeing constructed to'alord communication at a central point between saidchambers, 'and provision flor discharglng water oi" other liquid acrossthe communicating passage of said partition means.

2. The combination, in a centrifugal gas purifier, of a rotatable shaft,a plurality of rotary fans mounted on said.

g shaft, a casing inclosing said fans, a partition wall dividing theinteriorvof said casing into. a plurality of chambers each of which isoccupied by afan, said partition having a central opening affording.communication between said chambers, and provision for discharging wateror other liquid across said opening.

3. The combination', in a centrifugal gas purifier, of a rotatableshaft, a plurality of rotary fans mounted on said shaft, each of saidfans Vcomprising a central plate carrying vanes of diierent lengths onopposite sides, a casinginclosing said fans, partition means dividingthe interior of said casing into a plurality of chambers each of whichis occupied by a fan, said partition means being constructed to alfordcommunication between said chambers, and provision for discharging wateror other liquid across the communicating passage of said partitionmeans.

The -combinatiom in a centrifugal gas purifier, of a rotatable shaft,va plurality of rotary fans mounted on said shaft, each of said fanscomprising a central plate carrying vanes of different lengths onopposite sides, a casing inclosing said fans, a partition Wall dividingthe interior of said casing into a plurality of chambers each of whichis occupied by a fan, said partition having an opening atiordingcommunication between said chambers, and provision for discharging wateror other liquid across Asaid opening.

5. '.lhe combination, in a centrifugal gas purifier, of a rotatableshaft, a plurality of rotary fans mounted thereon, a casing nclcsingsaid fans, said casing having 4a division plate dividing the interiorinto a plurality of chambers, each occupied by a fan, said divisionplate having' a vertical passage in its upper part, and a supply pipecommunicating therewith whereby water orother liquid muy be dischargedacross the opening of said division plate.

6. The combination, in a centrifugal -gas purifier, of a rotatableshaft, a plurality of rotary fans mounted thereon, a casing inclosingsaid fans, said casing having a division plate dividingthe interior intoa plurality of chambers, e'ach occupied by a fansaid fans having vanesof one length upon one side and shorter vanes on the other, saiddivision plate having a vertical passage in its upper I part, Vand asupply pipe communicating therewith whereby water` or other liquid maybe discharged across the opening of said division plate.
